How to Run a Test

In order to obtain reliable and accurate results, correct capillary sampling collection technique is key.

• Always wear protective gloves• HemoCue® Hb 801 Microcuvettes are for single

use only • Follow local safety procedures for disposal of used

microcuvettes

How to Run a Test – Capillary Samples

Make sure the patient’s hand is warm and relaxed. Use the middle or ring finger for sampling – Avoid fingers with rings on. Sample at the side of the fingertip for best blood flow and comfort.

Clean the fingertip with disinfectant, and allow to dry.

Using your thumb, lightly press the finger from the top of the knuckle towards the fingertip to stimulate blood flow.

Press lightly towards the fingertip, and puncture using a high-flow lancet.

Wipe away the first 2 or 3 drops of blood. Press lightly towards the fingertip until another drop of blood appears.

How to Run a Test – Capillary SamplesFill the microcuvette. Make sure the blood drop is large enough to fill the microcuvette completely in one single step. Do not refill. Do not let more than 40 seconds pass between step 6 (filling) and step 9 (inserting the microcuvetteinto the microcuvette holder).

Wipe off excess blood from the outside of the microcuvette. Make sure that no blood is drawn out from the microcuvette.

Make a visual inspection. Precaution: If the microcuvette is not completely filled with blood, or if there are air bubbles, discard and fill a new microcuvette.

When a result is displayed, remove and discard the microcuvette. The result is displayed for 10 seconds after measurement. To change this setting, see section Connectivity and External Applications.

How to Run a Test – Venous Samples

• Use anticoagulant (K2-EDTA or Li-Heparin) • Venous samples can be stored and transported for up to 24 hours, at room

temperature or if in refrigerator before measuring• Make sure venous samples are properly mixed before use

How to Run a Test – Venous Samples

If refrigerated, allow the sample to reach operating conditions. Mix thoroughly on mixer for at least 2 minutes or invert manually 8-10 times.

When mixing controls, follow instructions for the control material used.

Place a drop of blood or control material onto a hydro-phobic surface, using a suitable transfer device.

Fill the microcuvette completely – in one single step. Do not refill.

Follow immediately steps 7-10 in section Measuring Capillary Blood, to perform the measurement. Do not let more than 40 seconds pass between filling and inserting the microcuvette into the microcuvette holder.

• An internal quality control (self-test) automatically verifies analyzer performance:

• Every time the analyzer is turned on• When the cuvette holder is put back into

place after removal• Every hour when in use

• Quality control and cleaning reminders can be set via HemoCue® 801 Connect

Quality Control

11GPM512INT 190423

If external quality control is required by local or other regulations, use liquid controls recommended by HemoCue

Troubleshooting

15GPM512INT 190423

Troubleshooting, cont.If the problem remains, the below Further Actions should be implemented. • If the problem still remains after Further Actions, contact the local distributor or

HemoCue AB

Perform Main Actions above.

Perform Main Actions above. Make sure to press down the microcuvette during measurement.

If the display shows --- instead of a result; fill a new microcuvette and perform a measurement, see section 8 or 9 in the Operating Manual.

Possible causes are e.g. incorrect sampling technique or incorrect mixing of sample. Fill a new microcuvette and perform a measurement, see section 8 or 9 in the Operating Manual. Check expiration date for the materials used. Make sure all result segments on the display are working properly, see section 5 in the Operating Manual.

The results is below (LLL) or above (HHH) measurement range.
